Abstract

Nanostructure of a metal-organic framework (MOF), {[Mg(HIDC)(H2O)2]·1.5H2O}n (1) (H3IDC = 4,5-imidazoledicarboxylic acid), was synthesized by a sonochemical method and characterized by scanning electron microscopy, X-ray powder diffraction, IR spectroscopy, and elemental analyses. The effect of concentration of starting reagents on size and morphology of nanostructured compound 1 has been studied. Calcination of the bulk powder and nanosized compound 1 at 650°C under air atmosphere yields MgO nanostructures. Results show that the size and morphology of the MgO nanoparticles are dependent upon the particles size of compound 1.
